I have done the trigger work on all our Glocks, also installed 3.5 connectors and spring kits, along with cleaning up any rough edges, triggers all pull smooth afterward, you can google up for aftermarket Glock parts, also instuctional videos on dissasembly/assembly, there is not much any simpler to strip than a Glock, just take your time, you may want to bench test with snap caps before actualy shooting the gun, however there really is nothing your going to be doing that you need a dremal for, so do yourself a favor and do not perform any work on the gun unless you completly understand what it does and why, most of the videos will tell you all this
