Ive looked it up on Google but a company will claim anything to sell a product. And I haven't seen a large number of this style firearm to show that it really works, so what I want to know is, do you think that compensated firearms truly recoil less? I mean in theory it all sounds well and good, but science can disprove the most solid sounding theories.
For example Ive shot two 40 caliber pistols, one compensated one not. The compensated pistol seemed much easier to shoot and get back on target. I then shot a 44 spcl revolver and that seemed easier yet, so I can't tell from personal experience. What are your thoughts on this?
Initial recoil is identical in non and comped weapons. The comp will dampen the rear and upward thrust as the bullet exits the muzzle, thus reducing the MOMENTUM of the initial recoil.
Until the bullet enters the comped area, recoil is identical. Only after the comp comes into play will the momentum be reduced. This results in much less FELT recoil (not actual recoil).
So yes, comps definately work
Life ain't worth living, if ya ain't got a good cigar.
Compensators work, assuming that they're designed correctly.
A minor part of the reduction in muzzle climb comes from the jet effect of gas coming out of the ports. Most of the effect comes from gas smacking into the front of the comp chamber(s). That pushes the pistol foward, reducing felt recoil and muzzle climb. Many comps made for action pistol competition have 2 or 3 chambers.
Compensators are a bad idea on defensive pistols. If you ever have to fire your gun from a "retention" position (close to your body, usually near your waist) the blast from the comp will hit your eyes - not good, especially if someone's trying to kill you and you need to see what's going on.
In a night shoot, the compensated firearm may give you more muzzle blast, or "flame effect", in your your line of sight. Can't speak from experience, but I've read an article on this, and the author had some comparison photos which illustrated it pretty good. This adds to Japle's input of a comped gun being not so good for personal defense purposes.
As far as your 40 Cal comparison to a 44 spl, that's not a good comparison. They won't shoot/perform/feel the same, as they are different to begin with.
