Overall Customer Rating of 32 Reviews:

The kit was high quality but the best part about this company is the detailed installation video. I followed it step by step. It was like working with a gunsmith. Everything went well and anywhere there was a problem, they told you about it which made me take extra care and patients and it worked out great. Cant wait to get out to the range.

Great product

Excellent product. Very easy to install. It took me less than an hour to install.

Light Primer Strikes and FTEs

Shot 115 gr FMC from Magtech, Sellier & Belloit and Winchester. All experienced an occasional light primer strike and FTEs.
I did the complete PF-9 mod. The gun shot perfectly prior to the mod. It ate everything and now it's acting up. Any suggestions as to what I should do or what ammo you have had 100% reliability with after a complete "upgrade" would be greatly appreciated.
Is there a sequence in reverting to OEM springs to resolve issues? e.g. replace hammer spring first or firing spring first then the trigger or firing pin.

Did all the PF9 mods

Did all the PF9 mods, trigger, springs, and recoil rod. What a difference! It's no longer painful to shoot. This gun has been totally transformed into a nice little shooter! Highly recommend.
