22lb recoil spring work for 45 Super?
- No text -
Blake and Kase know a lot about those on the 1911
The skinny is the recoil spring "system", along with custom barrel throating, and a chambered recoil reducing brake. Blake uses a special designed system that uses multiple progressive tuned springs. I can attest that it is one smooth shooting rig.
The heavy recoil spring really hammers your slide "notch" on the last round. Old military slides in particular. It can peen them pretty badly. I also found that the firing pin stop plate was originally designed as a square bottomed piece by John Browning and the military in WWI altered it to a beveled part so the GI's could rack the slide easier from hammer down. A square one slows the slide in recoil and racks the frame up less. I installed one on my 10mm and went back to a 18-19 lb. spring. I could not rack a round it was so stiff for me, even with the hammer already cocked. Arthritis and old age.
I've shot hot 10mm almost up to hot .45 Super specs. It's rough on a gun even set up for it. But it's for protection or hunting and in moderation it is fine. Increased maintenance compared to the low pressure rounds originally intended.
Thanks WB, was thinking of running the super
Sparingly in my Ruger American or Glock. Would like to find a good deal on a 1911, just a working piece not a BBq gun lol.
If you want a hot 1911, re-consider the 10mm
It's hot. If you load your own the original 200 gr. loading is easy to mimic. Cast gas check adds some speed at same pressures. In the 1911 bullet ojive shape can be a headache. I have a Glock set up for it and it will eat anything while the 1911 bobbles.
You can get a G21 Glock in .45 and with a simple barrel change and mag it becomes a 10mm. (You cannot reverse the idea on the G20) I even converted mine to shoot 9mm Luger! It's not everyone's cup of tea but an amazing platform.
Or get a good Ruger Single Action Revolver ..
have it built in a hot caliber if you want. Semi-auto's are just a fad and won't be around too long.

Just an idea... the full-size HK USP .45
... purportedly can handle +P and .45 Super with no conversion necessary according to info you amass thru your own research...
I have one of those, the Tactical USP
It's a BIG gun. It's still a plastic chassis though. I personally see my G21 as more robust as to taking a pounding. I am running a 26# spring under a custom Wolf barrel that has an extended throating. The bullet moves maybe 1/3" before hiting the rifling and beginning to build pressure. An old Roy Weatherby trick. I also have a Tri-port compensated brake on it. I've shot the 230 gr. at 1300 fps easily, I actually hit 1400 but backed off some. The barrel is 5.5".
I did some trigger work on it playing with less expensive alternatives to fancy drop in units. The gun shoots like a custom 1911 if you can hold it and work the trigger system. It puts a 1911 to shame as a simplistic machine but is very toolish.
The HK is too much ($1000) to screw with too a lot and the aftermarket is pretty thin. Most .45's can shoot limited +P and not be hurt much. The plastic frames flex and absorb lots of the beating, the whole thing is a buffer! Bad thing about HK is every 5 yrs. or so they come out with a new version and your old one is obsolete, and the $50 mags.
This is mainly for size reference. Right now the Glock has the stock 4-3/4" ACP barrel, the 1911 is actually a 10mm Javelina. I have barrels for the Glock to make it shoot 9mm, .40 S&W, 10mm, and .45 Super/Rowland besides the ACP.
