the story behind that sand test from years ago was the sand issues overseas - we tested the 1911 in 2 flavors, the HK USP tactical, and the Glock 21 - the results shocked everyone; up until that time I did not realize the open channel to the trigger mech was such a big issue in extreme environments - now I recommend a buttplug on all Glock’s as cheap insurance
I am confident that if we would have installed a buttplug on the G21 and ran the test again the results would have been different with the G21 doing alot better
In addition there had been tests conducted to determine if the USP and G21 would be suitable replacements to the 1911’s in use - every single Glock 21 had broken extractors during the testing and at a relatively low round count - this result dovetailed into what I had seen and heard elsewhere in the firearms industry at the time - the G21 had serious fleas and was to be avoided
Perhaps the newer G21’s are better guns - time will tell. I will watch and learn as I travel and train more shooters than all but a very select few of professional trainers - if there is a problem with a gun, optic, mount, ammo, etc. we hear about it and see it very early in the game
As of right now I cannot recommend Glock’s in calibers other than 9mm - period
If you want to ignore that advice that is an individual choice and more power to you - but anyone who knows me will tell you I don’t sugarcoat anything and that I am a straight shooter - as my friend Ken Hackathorn says about me ‘if you don’t want to hear the answer then don’t ask the question - cause Larry could care less if you like the answer or not’
be safe
