I have the 3.5 with birds head grip. Iv had it several years and not one malfunction other than bad ammo that usually fires on 2nd strike. And it holds it’s own in dollar bill competition. For the money I feel I got a tiny bit more than expected, Yes it’s a lot of alloy metal but it’s done right. It feels solid and is not bulky and over sized to make up for alloy strength. For its intended purpose or rather for what “ I “ see as it’s intended purpose, the price/product is hard to beat.
