Springfield Armory Hellcat RDP

by Dave Bahde

The flattest-shooting micro-compact on the streets

Micro-compact 9mm pistols with high capacity magazines and RDS (red-dot sight) capability continue to gain traction. Once limited to single-stack 6- or 7-round magazines, those days are in the rearview mirror. Ten rounds is now widely the minimum capacity, with fifteen rounds the current ceiling. These guns provide a generous payload while still being easy to conceal and comfortable for all-day carry. But there is always a tradeoff, and for most shooters that is muzzle rise. Stuff a +P 9mm into a 3- to 3.5-inch barreled polymer pistol and you can have yourself a handful; hard to control and not particularly pleasant to shoot for many. Also, red-dot sights are becoming widely available, but can be costly and many don’t seem to hold up well to the recoil abuse. Springfield Armory has come up with a very solid solution to combat micro-pistol drawbacks with the new Hellcat RDP. Adding a simple muzzle compensator, and creating their own line of durable red-dot sights, insures a high level of shootability, reliability and cost savings, making this a no-compromise, concealed-carry pistol.

The RDP model is equipped with a hammer forged barrel threaded to 1/2 x 28 and compact, easy to remove/install self-indexing compensator directly from the factory — a first for today’s high-capacity micro compact carry pistols. A thread protector is included should you decide to carry without the comp.

Hellcat RDP (Rapid Defense Package)

Being one of the first writers to test the original Hellcat allowed me to put an early Shield RMSc optic through its paces. Accurate, reliable, soft-shooting for such a small pistol, it really caught on and remains one of the most popular in its growing class. Very compact using the 11-round capacity standard magazine, and slightly larger with the 13-round magazine, it’s perfect for concealed carry. Early this year I was able to put a few hundred rounds through a standard Hellcat using a new Surefire weapon-mounted light during a media event at Gunsite Academy. Certainly not unpleasant to shoot, but using the 147-grain Federal it was a bit uncomfortable after high round count days. Springfield Armory has provided a solid fix for that in the RDP. Using the RMSc footprint it has a new Springfield Armory HEX WASP mini RDS pre-mounted from the factory, a threaded barrel, and a compact self-indexing compensator.

The new HEX WASP mini RDS is made from 6061 aluminum, has a hardened glass lens and an impressive 65,000-hour (7.4-year) battery life—especially considering the sight remains constantly on. Iron sights are a Tritium equipped U-Dot pattern and co-witness in the lower part of the RDS. The barrel remains hammer forged and Melonite coated, but is stretched to 3.8 inches and threaded to accept the proprietary, self-indexing compensator. Threaded 1/2 x 28 TPI, it will accept any matching 9mm suppressor. Removing the compensator requires no tools, spacers or shims and is accomplished in less than a minute. It goes back on just as fast, with proper timing and placement, using a simple and effective self-indexing lever mounted on the bottom.  The Gen 2 trigger fitted to the RDP model has been recontoured to provide more comfortable contact. Available with or without a manual safety, it ships in a nice little padded soft.

Like all other Hellcat’s, the RDP ships with one 11-round and one 13-round magazine, as well as a separate flush-fit baseplate. Also shown here is the Mission First Tactical Minimalist IWB holster, which is quickly becoming a staff favorite for comfortable and secure concealment of today’s new crop of micro compact pistols.

Testing Gear

Surefire’s Micro-Compact XSC is designed to work with the Hellcat and similar micro-compacts and was used during a large portion of testing, as well as every writer’s run in a recent Gunsite Academy shoot house event without failure. Rugged and lightweight, it has a 350-lumen output with a unique rechargeable battery design that snaps in and out without removing the light from the pistol.  Run time is listed as 30-minutes and the light has a “fuel” gauge to let you know when things are running low. A USB charging station is included and will hold two batteries.  The activation switch is slim but accessible, and is either momentary or constant.

Surefire’s Ryder Ti suppressor was also used. Longer than many, it remains light weight and slim, and does not obstruct either the iron sights or the RDS. Made from stainless steel with a Titanium outer tube, it will handle any 9mm pistol round and can be used on fixed barrels using their adapter. Threaded 1/2 x 28 and user serviceable it can also be used on rimfire rifles and pistols.

Especially noticeable with the hotter 124- and 147-grain loads, the Hellcat RDP’s 3-port compensator does its job very well, getting you back on target with a measurable increase in speed.

Range Time

This is the third Hellcat the author has tested, and like the others, the RDP ran without flaw, digesting everything it was fed — even while suppressed.

All of the Hellcat’s tested to date have been accurate and this one was no exception. Groups were fired at 25-yards using the HEX WASP RDS and a bag for a rest. The best group was just a bit under 2-inches using Wilson Combat 115-grain Barnes TAC-XP, but everything was in the 2 to 2.5-inch range. Moving to off hand at 15 yards the compensator seemed to make a noticeable difference, especially with the hot Federal 124-gr. +P and 147-gr. HST loads. A side by side comparison with a standard Hellcat revealed that the RDP had noticeably less muzzle rise. Spending the day with the same Federal 147-gr. AE used at the previous writer’s event, there was less wrist fatigue and rapid shots were easier to cluster at that range. This is a small pistol so a solid grip is best for accuracy but it is neither uncomfortable to shoot nor hard to be accurate with.

Round counts in testing these days are smaller given how hard it is to get ammunition, but it spit out 200 rounds of Federal American Eagle, and a 100 rounds of various carry ammunition without issue. This is the third Hellcat I’ve tested and they all have been 100% reliable with everything used, even frangible. Adding the suppressor did not change anything.

Sub-two-inch 25-yard/5-shot performance came with the Wilson Combat 115-gr. TAC-XPD load. Others also landed in the same ballpark.

Final Thoughts

The nicely contoured Gen 2 trigger was noticeably more comfortable to use, especially as the day progressed. Long days with previous Hellcats tended to wear on the trigger finger a bit, especially with my larger hands.

The muzzle compensator works without noticeably increasing blast at the shooter. There is some side venting but nothing you really noticed, not like you would see on some of the other comps out there. All in all, it does its job very well.

The new $299 HEX WASP sight worked very well, held up well, and never shifted or lost its zero. The lens glass is clear and has an anti-glare coating to remain clear in direct sunlight. Adjustment was easy, and a new seamless fill-plate is a nice touch if you decide to remove the RDS.

Springfield Armory has done a knockout job with the RDP, and it provides all of the attributes that many have been asking for: a small footprint, high capacity, RDS/co-witness night sights/compensator equipped micro pistol. And, with a retail of $899.00, you get all of this at a reasonable price. If you are in the market for a versatile and reliable micro-compact 9mm, be certain to add Springfield Armory’s RDP to the list.

With the Hellcat RDP also comes the recontoured Gen 2 trigger, and the pistol can be had either with (shown) or without an ambi manual thumb safety. The Adaptive Grip Texture works as advertised — the harder you squeeze the more your firing hand is locked into place.
