Hi all. Just bought an Ice Mag from DP and not sure if there is any way to get it to work with stock 16 round magazines. The mags won't seat. I wanted to try the gun in USPSA Limited this weekend and did not realize you need to order DP base pads to go with it. To late to get any and this is the last match of the year here in Illinois. at our local clubs. Any suggestions would be appreciated. I'm plan on using it as a backup to my STI and was hoping to see if it makes a significant difference before I invest $125 + to set up the mags. Thanks in advance for any help.....
