just acquired a Glock 23... haven't had one since my G22 in the mid-90's. since then, many companies have spurred up with products for the Glock besides Aro-Tek. So i need some help and/or suggestions from those who own the following parts: i'm gonna replace the guide rod and spring for an uncaptured setup so i can run both 40S&W and 357Sig. need a weighted rod, probably tungsten, and a good brand for recoil springs. mag well. looking for something at least manufactured in black, preferably weighted also. keep in mind, this is for a G23. reliable source for an original Glock smooth trigger with trigger bar, 3.5lb Glock sear, competition return spring, and reduced pull firing pin spring. a weighted tungsten firing pin would probably be in order to maintain pin release energy... any thoughts on that would be appreciated. Novak style iron sights, 3 dot preferred. no adjustables, no exceptions. competition Glock 23 +2 drop free mags that are compatible with the above mag well design. any other parts and suggestions are welcome. i'm looking to put this one into competition-ready mode for use as a secondary for defensive practical shooting/IPSC until i get my Sig Sauer GSR 45. or i may consider a G22 and go for mag interchangeability during competition... but i doubt this gun can be tuned to my liking i.e. converted to single action. thanks guys!
