Just a hint, last night I replaced the grips on a Browning High Power with some wood grips. All was well and I did a little fitting to allow the safety room. I tried to insert a mag and it wouldn't go. The wood needed to be sanded quite a bit before the magazine would insert easily and drop free. I think forcing the mag in would have cracked the grips.
Just happened to have a magazine there, I wouldn't have thought to check otherwise.
