I find that Glock handguns are reliable, and relatively inexpensive, but my largest compliant with them is the trigger. Having actually spent a decent sum of money on a 34 and a 35 (Refer to Attachment) with accessories like magazines wells, tungsten guide rods, bo-mar sights and JP Enterprise magazine release just to name a few.
I tried using them for the Limited and Limited 10 class competition in IPSC. No matter what I attempted I found that I still shoot faster and more accurately with my 1911’s (i.e. Splits) than I can with either one of my competition Glock’s.
If the intent were to use the Glock for self-defense then its OK I would even use it for IDPA or IPSC production class competition. But I would not recommend it for use in the IPSC Limited/Limited 10 Class. That’s my 2 cents.
