I have a newly purchased Gen 3 G20 that I bought used from a LGS. It is an amazing piece that I can group just under 2.5" at 50 yards using the stock Glock adjustable sights from a solid rest. I love to hunt with handguns. But, I do like optical sights for better hunting accuracy. I don't have large amounts of money to spend on getting my slide milled and so forth. Also, although I would love to have a G40 MOS, that's not an option either. My question is this: What is the best way to solidly mount a reflex sight to my G20 using the existing dovetail slide sight mount on my G20 10mm that will hold up to powerful loads for many 100s of rounds? I'm looking at purchasing one of the Burris Reflex sights or similarly priced reflex sights on the market.
