NOTE: as with the Hexsite review, i have posted this around the boards, but again, it is only because i love y'all and am tryin' to keep ya safe; very rare to find trick-merhcants who don't speak with forked tongue these days, but this stuff is the real deal as is Tim Sheehan. dig.

******************
i recently had a set of Goshen HexSites installed on my G20 (see review here) and am thusfar delighted with the results; but just when i thought it couldn't get any better, Tim at Goshen hips me to another little trick in his arsenal of unfair advantages which he doesn't advertise on the site: the "Keeper" integral muzzle brake (see pics of both and contact Tim at www.goshen-hexsite.com for more info, see closeups of my gun below).
the Keeper is basically an internal compensator, with side-mounted ports and internal baffles which A) brake recoil by providing a brief forward pressure on the barrel/slide just as the bullet is leaving the barrel; B) provide lateral stability by venting gasses thru the side vents while still being safe for clothing when fired from retention and bystanders when fired in close quarters by venting forward at a 30 degree angle and C) reduce muzzle climb by venting these gasses upward (assisted by the internal baffles) while avoiding the obvious caveats of top-mounted ports, such as flash in your line of sight and the dreaded spark-in-face disease.
infact, flash is effectively *reduced* by being dispersed from multiple holes and being directed away from line of sight, including less blast from the muzzle itself, just like a flash hider. but unlike an M16, you can stand right next to the muzzle without getting burnt.
any questions?
just kidding, but there's really not much more to say except that it works as claimed, and is even more effective the hotter your ammo; for my DoubleTap 165gr Gold Dot, the difference was night and day.
i tried it out down at Revere along with my new HexSites, and have to say they make a great team. the sights keep your eyes on target and the Keeper keeps the gun on it so all you have to do is pull the trigger. Tim claimed recoil in 10mm would be reduced to .40 range but i'd say it felt more like a 9 (i could literally feel the gun "quake" from the 10mm explosion happening inside, but without significant external movement, quite an odd sensation!) and in multiple shots on a shoot-n-c target, i could literally see the holes happening as i shot without ever having to re-acquire.
infact, my tendency to "zipper" upward with successive shots was was reversed, and some flaws in my technique were exposed: seems i pull shots more than i thought, because my follow-ups, though quick and on center - even *more* on center now with the Keeper - went successively *lower* with each shot. so i guess my best groups in the past might have been a result of my shot-pulling actually compensating for the somewhat pronounced muzzle climb of the stock G20.
what you'll get are very linear, vertical groups - no more fliers, but no more blaming the gun, which is shooting inherrently flat now - FLAT i say - and your shots are going wherever you point them.. yes, makes shots go where you point them, that's what it does..
"But Isn't It Loud?"
NOPE! no louder than a stock gun. i was shocked. it was the one thing i feared couldn't be gotten around, and put poor Tim thru seven shades of heck questioning him on the matter in advance, but here, as in all other aspects, it doesn't just defy the rules applying to standard porting and compensation systems, it *contradicts* them.
here's the deal: the blast, like the flash and the recoil, isn't just dispersed, it's "distributed" as the bullet passes thru the multiple chambers, so it changes the sound from a "boom" to a loud rumble - sounds crazy, but i swear it actually seems *quieter* than before, even in a closed stall.
recoil is distributed; flash is distributed; blast is distributed. the gun stays put.
Velocity, The Final Frontier..
i haven't had a chance to chrono it and no longer have a stock barrel for comparison, but Tim claims the system is about 80% efficient and only takes about 30fps off the top; if this is based on testing with his fave .45cal ammo, maybe i'm losing 50 or so with my 10mm based on that curve. just a wild guess, but suffice it to say you'll lose much less than if you just let some clown drill holes in your gun, and MUCH less than with that slide-mounted kitchen-sink Glock calls a "C", and still be able to C where yer shootin'..
this ain't yer grandfather's porting, nor some fireworks-generating "compensator" that'll help you in competiton but BURN you in combat - the Keeper is shootable ART which just might save your hide oneday.. and that's a beautiful thing..

here is a video of the full Goshen system (Keeper/HexSites) in action on a 1911 http://www.youtube.com/v/Y49HGp6igzI, and below are some pics of my Glock.
1st is a closeup of the ports, note the barrel ports are staggered behind the slide vents, both of which are angled up and forward - it's counterintuitve to think it brakes recoil while venting forward (you'd think it would make it worse), but recoil braking is accomplished primarily via the internal baffles: by the time gasses are exhausted the benefit has already occured. 1911 insert shows slightly different design for government model, which ustilises 3 smaller chambers due to different timing of gun, but benefit is similar with both designs. at bottom is my G20.
enjoy!
