Try Speer Gold Dot 135grn. hollow points. They are +P and the bullet is designed to expand out of 2" barrels. The part number to look for is, 23921. This is a Speer PN so it will be on the box end flap. Do a Google search on these bullets and you should have lots of info. they are sold in boxes of 20 each, and are more expensive than Regular ammo. (not hugely so though) BUT if you want protection out of a 38+P these are some of the best. They are what I use, I don't feel personal protection is an area I'm going to try "on the cheap". If you get them 2 boxes would be prudent, that way you can try them out to see what they are and still have enough to have to get the job done..
