Hello Wire Experts,   I have a line on a slightly used Uberti Carbine for a good price.  I'm thinking of buying it and getting it slicked up for my 11 year old and 8 year old to use in SASS matches.  Other than making sure it will hold 10 rounds (the seller says it will).  Are there any other characteristics of the carbine that impact its suitability for SASS matches?
