Bottom Line

At 1.70-inches for five shots at 25-yards, Federal’s 147-gr. HST load took home top honors from the bench.

Gemtech’s GM-9 is one of the lightest and thinnest suppressors tested. This made for a very handy setup, about perfect for home defense, or any applicable duty application.  Working around cars and within interior spaces it was fast and comfortable to use.   Recoil was manageable with one of the best carry loads on the market today.

Another advantage was cost, one of the lowest combined with the pistol, retailing at $599.99 and the GM-9 at $699.00. Street price is a couple hundred dollars less making it quite affordable. Both are proven designs from long standing companies with superb customer service and top-notch warranties making it an excellent choice. Contact Smith & Wesson; Tel.: (800) 331-0852; Web:
