I tried out my friend's G20 last week and was sold on the spot. However in my efforts to try and make every auto feel like a 1911 I found several companies that do grip modifications for Glocks. Of the one's that I have found I like the work of Burns Customs the best, and I was wondering if there are any perils that I should know about (besides voiding the warranty) before I start hacking into my wondergun. Specifically, will this affect frame strength or longevity etc. Also, does anyone know anything about this company. Thanks.
