and just going to stick with 11 rounds and leave the mags alone.
Probably a good idea, but I'd be interested to see how many the mag can fit. I've always wondered why they are so low capacity. I know ruger doesn't do hi cap, but it seems like a mag that big should hold 13-15 rds not 10-11.
I was checking my mags and the only difference is the groove on the side. The springs look like they may be of different material, but they have the same number of coils. The followers are identical as are the bases. I can see how the groove could adjust the stacking enough to cut cap by one round, but I don't see how they could be increased. Of course, I'm no engineer.
I have heard they make 12rd mags, but never seen a factory one. Don't think I'm gonna mess with mine. 1 rd isn't worth ruining a mag over to me. I have 4- 20rd, 4- 11rd and 3- 10rd. I just want some spare springs.
If you want more rounds there are 20rd aftermarkets that work well and they are cheap.
but I may have mentioned this already... dejavu...
