This is my first polymer .45 ACP handgun and it does not disappoint! So far, all I have put through this S&W is 150 rounds of TulAmmo 230 grain fmj and 50 rounds of Magtech 230 grain fmj, and not one single failure to fire, feed, or eject. At 25 yards and closer its as accurate as you are with the three white dot sights that come with it. The only two small complaints are that the magazines will hold eight rounds, but the seventh and eight round are a pain to load in the magazine, but over time it got easier, and the second complaint is that the trigger is pretty stiff, but with practice I got used to it. All in all this is a great handgun, and I shoot this one better than my RIA Rock Standard in .45 ACP, so I'm VERY happy, and I'll recommend this pistol to anybody looking for a four inch barrel, polymer, .45 caliber handgun.
