I'm switching back to carrying my 9mms during the summer and am using the Ranger-T 147gr's. After doing some research on youtube, I saw a few tests where they fully expanded. After doing further research, I learned that various Federal LE agencies only allow the use of that round out of their sub machine guns. After seeing the tests on youtube out of 4 inch barrels, I was thinking that using them in my P250 sub compact with less than a 4 inch barrel might not give me the desired results of full expansion. I was wondering what everything thought? I might end up switching to a 124 gr +p round as I can't find anything that says its only to use the +p+ Ranger Ts.
