I shoot and often carry the RI 1911 .22 TCM. This is a .22 Mag. on hormones. The new .22 weapons are like the .223 when the Military first adopted it. It was a loser would not be around long. Now after 50 years it is the most popular rifle in the Nation. The 5.7 and it's more powerful cousin the .22 TCM are very impressive.
