Since I heard so my horror stories about how tight they were, even those I have tools including a sight pusher I sent it to James at XD-HS200.com for 20 dollars wasn't worth my time. I had the sites but you can purchase them from him. He also did my gunkote .
I just got a MP Shield 9 and had AmeriGlo night sights installed, Galco I/W holster and 4 - 8 round mags. I will have a Apex trigger installed to match my M&P9 Pro and my M&P40 Compact.
I might do a stipple job but it is strictly a concealed carry only so no fancy color or bells and whistles. I might do Gold lettering on my M&P Pro that would be cool.
Polished the internals to smooth the trigger, polished the feed ramp and chamber, polished the magazines, and stippled the front and backstrap of the grip. Standsrd prcedures for any of my pistols.
One piece SS guide rods from ssguiderods.com I have the first 2 to come out, the gun cycles like butter now will have go pro video and torture test hopefully this weekend.
