Interesting pistol conversion.

The latest adaptations are a natural progression and are pretty neat. I figured they would have begun with the Glock myself. It's basically only the fire control system and the actions are all blow back.

That means the springs and bolt weight is specific for a set range of factory loaded ammunition. If you got goofy using reloads (which they clearly do not condone) you can blow a case in an extreme case. No pun. I have done just that on my ancient 1910 Winchester in .401 WSL.

But I applaud anyone with such an innovative idea they seem to have such well thought out and capitalized upon. I spent a considerable amount on my AR-9 carbine, which I enjoy very much. I see they may offer the platform in 10mm which is a rare opportunity and worthy of exploring. That's a HOT round for a blow back. Contrasting my 1910 Winchester is a 10mm Maximum, if you will, shooting a .408" 250 gr. bullet at 2000 fps from it's blow-back action. They did that in 1910!
