I doesn't help any for the folks with the Colt/Umarex platform, but the GSG-Sig 1911-22 guys might take note that you can quickly and easily change from 10-rd to 14-rd with replacement magazine followers that run around $5-$6 each.
Install/switchover is ridiculously quick and easy.
Use of the newly changed magazines is not quite as easy, but it is a 4-round increase and I find that it just makes a tremendous difference. Admittedly, it was a difference that I enjoyed
more before rimfire became like platinum.
