The Timney Alpha trigger has been in market for several years now. I have it installed on a glock and have not had any issues at the range nor during permit qualifications (few years).

That being said, I'm a pool of one. I'm wondering what the general prevailing, first hand experience, SF opinion is (I know there are differing opinions on the interwebz). I'm considering moving back to OEM. Mainly for parts inventory simplicity. Wondering what the pros/cons are for keeping the Alpha installed.

Reliability, Function, Issues/risks (for duty / carry). Other?

When I was a certified Glock Armorer for my agency, the only allowed alterations to the pistol were oversized mag releases, slide releases, and grip sleeves. Everything else was considered a possible liability (in court) should a firearm be used on duty. My personal pistols, however, did not fall under that umbrella!

Ok. Back to oem it is then.

The Glock Performance Trigger is OEM and based on Timney's design. Costs a lot less too.

If I have Timney installed, is there sufficient cause to switch? I have no familiarity or experience with the Glock version.

For carry/duty, Leaning toward stock but Timney is possible and sounds like glock performance is another alternative.

If you're allowed & comfortable running the Timney in your duty weapon, then do it. Train w/ it, know it, own it.

Your "cause to switch" would be your or your dept's policy against having aftermarket triggers in duty weapons. The GPT is a way around that in that you can get Timney-like performance while keeping parts OEM. Depending on which springs & connector you install, you can get a GPT to run very close to if not virtually identical to a Timney.

One con to the Timney & GPT is that they require more frequent cleaning & lubrication. The GPT manual states, "To ensure optimal performance, GLOCK recommends lubrication using a quality CLP oil or equivalent prior to first use, and before and after each subsequent use of the GLOCK Performance Trigger."

If you regularly clean & lube your Glock, it's a non-issue, but if you're the type who never does - and let's be real, there are many LEOs who never maintain their sidearms - then you're better off w/ the stock trigger.
