Check to see if the carbine will hold ten rounds of the longer cartridge. I normally load 38's at 1.45" for the wife's carbine with no issues.
Accidentally loaded some closer to 1.50" once and found out at a match that the 10th round wouldn't quite push all the way into the magazine.
I have since trimmed off the magazine spring to a minimum length I dare to and it will hold ten rounds of 1.50".
