I love mine in 4.2"! I'm not sure why I bought it, other than I already had a GP-100 and Super Redhawk, and it just made sense to have "small, medium, and large" versions of basically the same firearm. For target shooting, it likes everything from primo factory .327 Fed down to my crappy cast boolit 32 S&W Long reloads.

Read this:

This can give you an idea on prices. Used ones are typically the same price on Gunbroker.

Ummm... that was the whole purpose behind the design of the .327 Federal - to try to match the muzzle energy of the .357 magnum in the smaller cross-section (thus better penetrating) .32 caliber!

The lighter bullet etc means lighter recoil than the .357mag in similar-power loads as well, in part because it takes a tad longer to reach that higher max chamber pressure*, thus the recoil impulse is spread out over a fraction more time with a lower peak recoil.


* .327Fed: 45,000psi
Ballistic performance
Bullet mass/type Velocity Energy
100 gr (6 g) JHP 1,400 ft/s (430 m/s) 435 ft⋅lbf (590 J)
115 gr (7 g) JHP 1,300 ft/s (400 m/s) 431 ft⋅lbf (584 J)
100 gr (6 g) JHP* 1,655 ft/s (504 m/s) 640 ft⋅lbf (870 J)
115 gr (7 g) JHP* 1,587 ft/s (484 m/s) 620 ft⋅lbf (840 J)
Test barrel length: 3 1/16", * 5" Blackhawk Revolver
.327 recoil energy: 5.62 ft⋅lbf (7.62 J) with 115 gr (7.5 g; 0.26 oz) JHP

.357mag: 35,000psi
Ballistic performance
Bullet mass/type Velocity Energy
125 gr (8 g) JHP Federal 1,450 ft/s (440 m/s) 583 ft⋅lbf (790 J)
158 gr (10 g) JHP Federal 1,240 ft/s (380 m/s) 539 ft⋅lbf (731 J)
Test barrel length: 4 in (102 mm) (vented)
.357 Magnum recoil energy: 7.22 ft⋅lbf (9.79 J) with 125 gr (8.1 g; 0.29 oz) JHP


So it looks like in a 4.2" barrel the .327Fed would have ~525-537 ft lbf vs the .357mag's 539-583 ft lbf... ~92%-98% of the muzzle energy with only 78% of the recoil energy!
