Recommendation sought for Gen.4 Glock grip plug

[PatEgan]

I'm looking for recommendations on a grip plug for a Gen.4 Glock that could accommodate the grip inserts. The Pearce is the only one I'm aware of that can be used in conjunction with the inserts, but are there any that offer a bit of a bevel on the inside surface to aid in mag changes?
Thanks,
Pat

I like the Pierce part; fits well and backstraps are still usable. That being said, I've not seen anything like what you describe.
