View Full Version : 10mm --> 9mm

September 4, 2007, 06:05 AM
Has anyone converted a 10mm to 9mm? I've got a hankering for something like a G20 or Delta Elite (leaning more towards the G20), but I want to be able to sell my 9mm and just get a barrel/mag or conversion kit to shoot 9mm since I won't always be able to afford the "big dogs".

I'm also curious how much accuracy might suffer considering differing trajectories vs. fixed sites. Is that concern well-founded or a non-issue?

You can do it with a EAA witness 10mm(just by conversion kit)

For Glock, check storm lake barrels(i think the are the most recommended on GT) or lonewolf products

Can't be done with a Glock.

You could get either and buy a conversion kit for 22LR for really cheap shooting, and fun too.


These guys make good ones, the best for Glock IMO.

I don't think you can convert a Glock 20 to 9mm, but I know you can convert it to .40, which is almost as cheap and common as 9mm in many places.

OOPS! I thought I read somewhere that you could with the Glock....Sorry:o

I can't find anyone making conversion barrels anymore, but you used to be able to buy 9mm conversion barrels for the G20. Extraction wasn't guaranteed to be 100% but the reports I heard were good.
