I just got back from my first range session with my new S&W M&P 45 ACP. This model has the night sites, the thumb safety and no magazine safety. I loaded ONE round (my first shot with a new gun is always ONE round, just in case the darned thing tries to blow up in my hand). That round went directly into the center of the bull's eye at 21 feet. I about packed up and went home right then! "Ayup, that's all I need to know." Instead, I put about 75 rounds of factory 230 FMJ and 185-230 HPs through the pistol--all without a hitch. The gun did NOT work with my dad's LSWC reloads, but he loads these for HIS guns and they are notorious for being over sized in most other guns. No worries. Lesson learned.
I put the over sized LSWCs aside and fired strong hand only and week hand only without a hitch. Everything went in tight little groups at 21 feet. So, I hung a B27 target and rolled it out to 75 feet. I fired 5 rounds each at every target distance including SHO and WHO at 21 feet and 5 rounds at 15 feet so fast the range officer blinked the lights and gave me the I'm-gonna-cut-your-throat-if-you-do-that-again sign. I scored 94% on points and 100% if you count everything inside the 8 rings as a hit. No missing shots. No stray shots. I only had 5 rounds just into the 8 ring lower left (typical for me).
The trigger is fine as is. The night sights are awesome. The gun weighs 36 oz. loaded (that's 10 oz. lighter than the S&W 645 I'm replacing). Recoil did NOT hurt my hand (and that's a special problem for me as even the Ruger P345 and Glock 19 hurt my hands). The safety works perfectly and I even like the all black finish that will hide well against a black t-shirt.
I'm so taken with this firearm that if the reliability continues for 500 rounds, I will probably make this my ONE GUN and have my name inscribed on the top of the slide.
