smolphry Posted April 8, 2018 Share Posted April 8, 2018 (edited) I'm planning on building an open gun on an m&p 2.0 for steel challenge and uspsa. I realize it's not the ideal platform but as someone who doesn't reload and is working with a budget it's the direction I'm heading. My question is on slide/barrel length. Since sight radius is irrelevant is there any advantage in going with the 5" gun over the 4.25? My though is that the lighter slide may cycle better with factory loads, can anyone shed a little more light on the situation?

aandabooks Posted April 8, 2018 Share Posted April 8, 2018 The 4.25" will be easier to get a threaded barrel for. Without reloading up toward major your not going to get much from the comp. Carver probably has everything you'll need. I did one in .357sig from a .40 gun and used all Carver stuff minus the Storm Lake barrel. Link to comment Share on other sites More sharing options...
smolphry Posted April 8, 2018 Author Share Posted April 8, 2018 Thanks for the tip. Carver is the plan for everything. I know I won't get the full effect from the comp, I'm looking for it as more of something to tinker and have fun with than to win matches with.

HCH Posted April 9, 2018 Share Posted April 9, 2018 You sound like the perfect candidate for Carry Optics. And I would go with the shorter slide.. the pistol should be cheaper and easier to find. Link to comment Share on other sites More sharing options...
zzt Posted April 9, 2018 Share Posted April 9, 2018 Carver uses KKM barrels that are a tad shorter than normal so there is not an unsightly gap between the comp and the slide. You want a 5" barrel, because it is easier to make Major with it. You can buy 9mm Major ammo from three places online. I'm not sure whether anyone sells 115gr loaded, but two sell 124 and one sells 147. You definitely want the 124s. I shot with a friend yesterday. He was shooting a 5" M&P with Carter's open stuff on it. It was his first time shooting Open. He did well except for a lot of find the dot. He had previously shot CO and was used to slide mounted optics. With a Carver bridge mount and a Slideride the dot is so far above the bore, he had trouble picking up the dot. It will take him a week or so of dry fire to get used to drawing the new setup. Link to comment Share on other sites More sharing options...
