I normally carry a Gen4 Glock 17 or 19 MOS with an RMR06 on top. The only mods I really make is an OEM (-) connector, grip plug and a Grip Force Adapter. I'm interested in trying USPSA Carry Optics and I want to learn about mods to gain a competitive edge.
1) Grip Force Adapter: can I use this? The rules are kinda vague about this. If I have to use the Glock OEM back straps, can I mod them (ie cut) to fit the same profile as the GFA?
2) Recoil Spring and Rod: As I understand this, you want a heavy guide rod to keep the nose of the gun down; a weaker spring to minimize the slide shooting forward and pointing down the nose of the gun when it goes into battery? Factory is 17 lbs.
3) Striker Spring: Reduce the weight of the spring to reduce trigger weight? Factor is 5.5 lbs.
4) Trigger: I was just going to us Apex Tactical since they are in town. Anything better?
5) Magazine: Carry Optics allow 140 mm mags. Use the Magpul 21 round mags OR mod my OEM mags with something like Taran Tactical +5 extension?
6) Optic: I was going to use the Vortex Venom (which I have used a lot) though the DPP looks worthwhile to try.
Thanks in advance for any help.
