Have fired the Colt 1908's and Baby Brownings "on the range". Have also shot and chronoed the Walther TPH .22 LR --Just like USP9's TPH in 25ACP, only in 22 LR. Far more common, not that any TPH is abundant. All lot's of grin and giggles. The TPH's are darn accurate. I took lots of quarters from fellow pilots on bets on hitting match heads at about 7 yards.
Now my .25 ACP tale of Woe
Favorite cousin (about 4 yrs older) was a deputy sheriff. Carried a Colt .25 as a backup. I had gotten a "Chorny" brand chronograph within a year of it's intorduction, and this is several years later (so say 1992 or so). He wondered what that little 25 could do, so conned me into loaning him the Chrony. Yep. He Shot the Chorny
Hit it just left of center on the "back plate" of the front half. [The "Chorny" folds in half for storage, so there is a divider "plate" half way between the screens due to this] It completely chipped off the paint of a 3/4 in high by 2 in wide area. Buckled the sheet metal about 1/2 inch. Didn't penetrate or break through the sheet metal. Was able to use some "duck bill" pliers to pretty much squeeze the metal back out flat. Just now have re measured the metal with a 1 inch mic. It's .041 in thick, including the enamal paint.
Walther TPH 22 LR chorno results: Tests at 12 feet from muzzle between 60 and 80 deg F, 750 Ft MSL. Test Ammos: Fed "550 rd Bulk Pack" 36 gn plated HP; Rem "Golden Bullet" 36gn HP; CCI Minimag 40gn RN; Win SuperX 40 gn RN; Win Dynapoint HP; Rem Thunderbolt 40gn; Federal American Eagle 36gn HP All "High Speed" Ammo types.
Vel 860 to 880 fps It all falls in that band.
CCI Stinger 960 fps
tests repeated multiple times over several years.
Moral: 22 LR out of a .25 ACP length barrel is faster than most cowboy loads and at the high end for 45 ACP Ball. Don't bet prison that it can't hurt someone. It and .25 ACP might not be a great choice though. And, if you do stupidly loan your chorongraph to someone, hope he's using 25 ACP
