Can u modify a g21 mag to 10mm?

Can a g21 mag be modified to 10mm?

Cool i never thought of that !!

I have a G-24C long slide that i used to carry, very easy to shoot, muzzel blast is minamal & is very accurate. Great trigger. Allas!!!! i bought a G-29 so the 24C is now a safe gun. Love my G-29 & carry all the time . Also have a G-21 converted to 10mm with a 5.30" Storm Lake barrel also very accurate but not as nice of trigger as the 24C. This is my woods carry.

I'm a NRA life member !

...why, most of us, look to purchase an aftermarket barrel.

For me it is about going to a 6.02" version to add velocity in 10mm.

My thoughts exactly 

I've got to try the 40sw in my g21 x 10mm conv. barrel !!

So, if i bought a 10mm long slide, would it fit my G-21 frame?

Does the G-29sf with the extended grip have the same size grip as the G-20sf?

Ruger Supper Blackhawk 44 mag, Para LDA 45 ACP, Thompson Contender 44mag, G-21 45 ACP & 10mm, 

Gee! Haven't had any problems with my g-21 slide.   

Yes !  I have a g21 converted to 10mm & it runs fine. The newer gen.3  g21 extractors were upgraded from gen.2 & should work fine.

I was reading somewhere that the gen 3  g21's had a updated  extractor that works well with 10mm conv. that i already have in my g21. I was hoping to conv. the g21 to 40sw also.

Nobody makes a conversion barrel (40sw) for a g-21?  But they do for a g20 

G-21 with a Storm Lake 10mm barrel. Does this count?
