Glocks are simple to work on. If you get dawson sights, they include the tool to install them. The vanek and glocktriggers.com triggers are both top notch and drop right in. I have the vanek in a limited glock and the glocktriggers in my production one. I added a jager striker to both and they make a good trigger feel even better and crisper. When you order a trigger, just call and ask for the production legal one. Both charlie vanek and jeff wilson (glock triggers) are easy to talk to and can explain their triggers to you. On the grip, I would try the griptape first then if you want to shoot IDPA it is SSP legal. A 3/32 pin punch is all you need to detail strip the glock.
