I don't mind spending some money to get a receiver fitted to my slide. I have some money I tot the gun as it is with the Barsto barrel and sights etc. it was a nice IPSC gun when I could use it as a hicap gun. I'm thinking of getting back into IPSC and shoot single stack class and my upper as a single stack would be a awesome set up. Probably would get a Caspian receiver. I'm going to call Dawson Precision tomorrow to see it they would do it. But they look like they have gone more of the retail of guns already set up and not building guns. May also call EGW they built my first IPSC gun.
