I’ve been shooting for 10 years and I’m picky about where I buy accessories online. polymer80warehouse.com earned my business. The Order Buy Full Auto Glock Switch Online arrived in 3 days, packaged well, and fit my G23 without any modification. I put 141 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.
