Looking for information on the 22 Corbin Flea. It was developed by Dave Corbin In the early 70's, he wrote an article in one of the Gun Magazines might have been reprinted in annual for that year. Would like to know which magazine name and date. It told how exactly he modified a Browning !922 to fire it. He has some information on his pistol grip site he used longer heavier slide extension. Some where else said he used a stronger recoil spring. Would like the magazine it had more exact information. Contacted Dave Corbin by email several years ago but he no longer knew which magazine and only remembered generally how the Browning was modified. I have several 1922's and would like to modify one to 22 Flea
