Yes sir. Glocks for sure can be greatly improved by novices. There are tons of videos available and since the build at home pistols are mostly based on them, there are a lot of helps to "tweak" them.I bet my gunsmith can give it a good old fashioned trigger job. I don't normally buy kits I usually take it to him. Aside from hammer fired or rifles I've never ask him about striker fired. Is it possible for a gunsmith to work over the original parts on striker fired weapons to get a better trigger?
