As good as all the others I've got here. This batch should make my pile sufficient for my needs. For now. Probably. Haven't had the opportunity to put them to work yet, but test fitting into my firearm was perfect. Dropped free on release without issue. Once I can get my mag extensions in place, they should be perfect. (They give the appearance of 20-rnd mags, but original capacity remains unchanged) Wholeheartedly recommended, especially with the sale pricing.
