I was on E A Brown WEB site and saw the Pentax scope for sale for $70 bucks I purchased it and placed it on my Glock 20 as pictured. 500 rounds of Beartooth 230 WFNCG at 1350 FPS and its still going strong and shooting to pint of aim.

It should be fine, put it on something bigger, you got yourself some scrap.

Any feeding issues with extra weight on slide? Might make a hunting gun out of one of my Glock 20s. Red dot comes to mind.
