Don't buy for a P80 build!
Bought this for a P80 build in conjunction with a Brownells G19 slide. Bottom line don't do it! After assembling the slide and dropping in the barrel, I decided to run it on top of my Glock factory frame to confirm function. Went to the range, and put about 50 rounds of Winchester 115gr through it. No issues. To verify function of the assembled P80, I used my Glock factory slide and barrel on that. 50 rounds, no issues. Then put the Brownells slide w/Agency barrel on the P80. Preformed function check. Issues when racking the slide multiple times, it didn't feel or sound right. Disassembled the firearm and inspected everything. Excessive wear and deformation on the bottom of the chamber. Sent an email to Agency, and was basically told that their barrels will wear excessively with a P80 because the slide rails are tougher than Glock factory, and said that Brownells slides also cause problems due to varying tolerances. Basically telling me that I was SOL. I've had no problems at all with the Brownells slide mind you, I find their product to have excellent fit and finish. This is Agency's issue.
