I need a little advice on my next mag purchase. I have a Kimber Custom Classic which was giving me some feeding problems so I purchased a Wilson 47C mag and walah,end of feeding problem. My dilema is I'd like to get some more but I'm planning on adding an extended magwell,from Wilson, and was wondering what would be the best, the.350" basepad or the .625".I want it long enough to get a good "seat" with the magwell extension but not longer than neccessary.Also don't know whether to stick with the 7-rounders or the eights? Are the plastic base pads easily broken? Fear of this is why I originally went with the metal base pads but I know the low profile "steel" base pads would be harder to seat. Any advice would be appreciated.
