My Glock experience has now come full circle. Over 20 years ago (25?) I started off with a Glock 21. Kept that several years. Toyed with a Corbon 400 conversion on it that did nothing but jam.
Sold it, and moved to a Glock 20. Kept that (still have it) a little over 20 years.
I have purchased in the last few months a G20SF, G23C, G32, and about every conversion barrel for each of them.
Today I purchased a G21 conversion kit with night sights for $275 on eBay.
I really enjoy the Glock pistols. Will be good to send a few rounds of 45 down the range again.
