jsneff Posted April 12, 2014 Share Posted April 12, 2014 So I finally spent several hours installing my Powder River Ultimate Drop-In Kit in my XDm 5.25. Time we'll spent(and their videos are very helpful, if a bit fast on the fitting dis/reassembling) as I got really good at taking the pistol apart and putting it back together. Had to reduce grip safety edge on the sear and the over travel bump on the trigger. The sear side and safety functioned perfectly and I shot 200+ trouble free rounds at the range immediately after the successful install. Now the bad part, I am getting a trigger pull in the mid 5's on my RCBS spring powered trigger gauge. I didn't check the factory trigger as I was committed to this trigger install any way, but think I will because I don't think it is any heavier than this PRP "Ultimate" trigger. Their video shows a 4Lb pull. I would like some input from those out there with PRP triggers, because I think I got a dud. Link to comment Share on other sites More sharing options...
bobert1 Posted April 13, 2014 Share Posted April 13, 2014 (edited) Mine is at 3.6 #'s It does take a lot of trigger pulls to smooth it out. Edited April 13, 2014 by bobert1 Link to comment Share on other sites More sharing options...
joshxdm9 Posted April 13, 2014 Share Posted April 13, 2014 I installed the same trigger in a xdm 5.25 9mm. I checked my stock trigger at just over 6# after install of the same kit it Brock at first around 4.5# I did a little more work on the sear and a little polishing. After a few hundred rounds in practice it breaks very clean at 3# Link to comment Share on other sites More sharing options...
aandabooks Posted April 13, 2014 Share Posted April 13, 2014 Mine is at 3.5lbs after about 500 rounds. I spent alot of time stoning the parts before installing them and didn't just work on the fit points. Link to comment Share on other sites More sharing options...
dave33 Posted April 14, 2014 Share Posted April 14, 2014 I installed a regular PRP drop in kit and used the blue competition springs that came with it and my trigger breaks just over 3 lbs. I didn't polish or do anything besides just dropping in the new parts. Im totally pleased after countless thousands of rounds. Link to comment Share on other sites More sharing options...
shoozen Posted April 20, 2014 Share Posted April 20, 2014 Have installed two now and have suspicions that they might be a bit heavier than I expected originally. I don't have a gauge, though. Good to hear that it mellows with age, like the rest of us. :-) So @aandabooks: Please say more about some of the other points that you've worked on. I pretty much stuck to the video directions, but would like to know more. Link to comment Share on other sites More sharing options...
aandabooks Posted April 29, 2014 Share Posted April 29, 2014 Even though it doesn't show to do the sides of the piece that activates the grip safety, I lightly stoned the sides to insure the least friction between it and the part next to it. I switched to the stainless pins and spun them on a lathe with emory cloth to insure they were burr free and as polished as I could get them. Just a little extra time but trying to make everything as interference free as possible. Link to comment Share on other sites More sharing options...
johnbu Posted July 7, 2014 Share Posted July 7, 2014 Here's some pics of what I did while installing. Light smoothing of machining marks in the striker channel. Higher shine on the striker at the edge grabbed by the sear. Same shine on the sear where it grabbs the striker Also polished the striker body to a high shine, but didn't photo that. The improvement in feel smoothness was great and it seemed to lighten the pull too, but I don't have a guage. Link to comment Share on other sites More sharing options...
mpeltier Posted July 8, 2014 Share Posted July 8, 2014 Did your kit come with 2 trigger springs? They make a competition trigger spring and a heavy one. My kit came with the heavy one. I had to call them to get the lighter competition spring. I also polished every contact spot in the entire fire control assembly as well as the striker. Replaced the striker safety with a titanium part and ended up with about 2.75 lbs on my trigger scale. Link to comment Share on other sites More sharing options...
JGus Posted July 19, 2014 Share Posted July 19, 2014 I installed the Ultimate as well and have a very smooth 3.3# pull. I was even more impressed with the incredibly improved trigger reset. Don't forget that huge improvement with the installation. Link to comment Share on other sites More sharing options...
cfussell Posted July 21, 2014 Share Posted July 21, 2014 I installed the PRP drop-in kit in my xdm. Measuring the trigger pull with a rcbs spring gauge it was six pounds with a long trigger pull and reset. After the install it is three to three and one-quarter lbs. I used the blue springs not the combat springs. It is by far the best trigger on a semi-auto that I have ever had or shot. It took some time to get used to it after the install. You had better be ready to shoot when you touch the dingus on the trigger because its going to fire. No light strikes or anything it just shoots.
