Being it is made by EGW I'm sure it's a quality product, but I think I prefer the styling of the Dawson Precision magwell and the way it hooks over the front of the grip instead of leaving the front sort of bare looking.
I do like the smooth surface of the EGW magwell better though than the ribbed surface on the DP.
It's good that more aftermarket parts for the Prodigy are slowly becoming available. Having more choices is a good thing.
