Hi,
MCK Chasis is great for Glock. I had immense amount of fun with it and significantly increase capability of your Glock. I would say it is a much more budget-friendly approach to pistol carbine than buying new carbine. Keep in mind that it is all plastic. I hope this helps!

Steven, Gimmick, fun, lightweight. Plastic parts can break pretty easy and the plastic grooves that go in the slide to mount pistol in chassis can chip away and break. They are fun and well worth the money. I have them for Glocks and Sigs. Get an adjustable one that fits the G19 and G17 size. And BUDs has the best price on them out there.----------budsgunshop.com/product_info.php/products_id/714020729/caa+micro+conversion+kit+mck+glock+17%2f19%2f19x%2f22%2f23%2f31%2f32%2f45
