Production division modifications
I've been working my new M&P9 to replace my Beretta 92FS as a competition gun. I shoot USPSA, so what can I not change? I want to add the following:
•APEX Hard Sear (9 mm, .357 Sig & .40 series) - NOT FOR .45 ACP
•APEX M&P Ultimate Striker Block Kit (USB kit)
•APEX M&P Increased Rate Sear Spring** (very small) & Trigger Return Spring
I shoot production, so can I add all this and be okay?
Yes. Internal modifications to improve accuracy, reliability and function are allowed. The relevant portions of the rule book are quoted below. The entire rule book can be found at
United States Practical Shooting Association.
Authorized modifications
(Strictly limited to these
items and their stated
guidelines)
•Internal throating and polishing to improve accuracy,
reliability and function

the same length, contour, and caliber as original factory
standard.
