Loki999 Posted February 28, 2011 Share Posted February 28, 2011 Hi all, I've been shooting a fullsize svi with 3 holes in the barrel and a titanium 3 chamber comp. Now im switching to the imm open and i wonder if you get a total different gun if you put 3 or 4 holes in the barrel. Who has expiremented with the holes and did you liked it or why not.

GentlemanJim Posted February 28, 2011 Share Posted February 28, 2011 Havin shot an IMM with 4 holes for two years It worked very well, but also rang my ears with double plugs. I had to go to a 5" gun with no holes to protect my remaining hearing Jim Link to comment Share on other sites More sharing options...
Loki999 Posted February 28, 2011 Author Share Posted February 28, 2011 Yes they are very loud, i think i will try it for a little without the holes. But eventualy i will put 3 or 4 in the barrel. Anyone expiremented like this? Link to comment Share on other sites More sharing options...
lcs Posted February 28, 2011 Share Posted February 28, 2011 Yes they are very loud, i think i will try it for a little without the holes. But eventualy i will put 3 or 4 in the barrel. Anyone expiremented like this? Very loud IMM with holes. I have 4 holes in my open, but they are about 1/3 size of the IMM holes. Mine are about the size of a Brazos gun holes and I don't think it is any louder than a normal open. In additon, it takes a heck of lot more powder for the IMM. You are pretty much filling the case.

Loki999 Posted February 28, 2011 Author Share Posted February 28, 2011 Im wondering iff there are shooters who shoot an imm without holes, i think it's designed to be a flat shooting more backwards kicking gun., so you need holes right? Link to comment Share on other sites More sharing options...
lneel Posted February 28, 2011 Share Posted February 28, 2011 The Team Infinity shooters are all using either 3 or 4 holes. I prefer 3 and use Winchester AutoComp (fills the case about 70%) and it isn't too loud (well, all open guns are loud). Lee Link to comment Share on other sites More sharing options...
Foxbat Posted February 28, 2011 Share Posted February 28, 2011 Im wondering iff there are shooters who shoot an imm without holes, i think it's designed to be a flat shooting more backwards kicking gun., so you need holes right? I shoot an IMM without holes, and I also shoot two similarly sized guns of a different make with two sizable holes - picture of one attached. There is no big difference, but the ones with holes do shoot a bit flatter. All three in 38 SC. Link to comment Share on other sites More sharing options...
Rolex Posted February 28, 2011 Share Posted February 28, 2011 I have been shooting my open gun with two holes, but then I don't know any thing else! Link to comment Share on other sites More sharing options...
Loki999 Posted March 1, 2011 Author Share Posted March 1, 2011 Ok now i learned that it's not only the holes that work on my buddy's IMM. But he has also lightend the slide and shoots with a cut off 8#spring. 9,6 grain VV 3n38 124 grain hornady federal small magnum primer. I asked my gunsmith and he doesnt believe in slidelightening, his believes in training a lot... I guess there are no shortcuts, and there are a lot of factors to be experimented with.

bill d Posted March 1, 2011 Share Posted March 1, 2011 Loki, If you are going to get an SV IMM (which is a great choice) then I suggest trying a 4 port barrel with their 2 port Ti comp. This is the flattest shooting gun I've shot yet. I have tried many different barrel port configurations and none have performed as well as this set up. The weight of their guns is also centralized which gives a well balanced feel. This attribute allows for more precise transitions and a lot better/confident feel when shooting on the move. Some guns feel balanced when you hold them but when you actually shoot them you will notice a difference. I highly recommend getting an IMM with the 4 port barrel and 2 port Ti comp.

Loki999 Posted March 1, 2011 Author Share Posted March 1, 2011 Hi Bill, Did you also cut the slide? I'm a little affraid of this because i think this little gun is taking a beating enough with major ammo. Link to comment Share on other sites More sharing options...
Don_B Posted March 1, 2011 Share Posted March 1, 2011 You did not specify if you are shooting 38 super or 9mm. I have been shooting a IMM 9mm for several years and have 2 hybrid ports. It will be difficult to make major in 9mm with more than 2 ports. In 38 super you can definitely have 3 or more ports. My original 38 super IMM had 6 ports! It was extremely flat shooting but also EXTREMELY loud. Just be aware that the more ports you have the more powder you will have to use which will result in a louder gun. You can always put more ports in a gun but it will be dificult to take any of them out. The slide on a IMM is already as light as it should be. You will lose reliability if you go lighter.

bill d Posted March 1, 2011 Share Posted March 1, 2011 Loki, my slide has the rear swooped with a slide racker installed. As for more lightening, the gun is about.500 shorter and there is material removed for the hybrid rib (ports), then the rear swoop. This lightens the gun to a certain number for the gun to operate effectively. Infinity has done a lot or R&D work and they use an optimal slide weight which works very well for the gun without hurting the integrity and longevity of the gun with major loads. I used to do a lot of lightening cuts but, to a point, gained nothing but aesthetics. You want to remove some weight, but you are correct that taking to much away can be a issue with durability. If you are attending any major matches(mostly east coast and central), I'm more than willing to allow you to burn some rounds on my gun. Infinity's platform is a runner........... Give Brandon a call. He'll gladly answer any questions. My gun is also in 38 Super comp................. Link to comment Share on other sites More sharing options...
pjb45 Posted March 1, 2011 Share Posted March 1, 2011 I have an older SV with six ports! Shots really flat and really soft. It is definitly painful for the RO, I do not noticed anything but I use gel pads on my MSA muffs. It is at Infinity now get a new metal grip put on it. Call Brandon and chat with him or Call Chris T and ask his opinion. Kodiak Precision is one of the few SV gunsmiths. Call Don. Don also did the trigger job. As whatmeworry says, you need a cigarette afterwards. It is that good. Link to comment Share on other sites More sharing options...
calishootr Posted March 1, 2011 Share Posted March 1, 2011 i shot a first gen IMM gun a while back, andthe thing i did notice was that it was LOUD...and more concerningto me, was thatthe 'shockwave' instead of being around me and basically punishing the RO's, stopped right at my chest, sort of felt like someone with a big rubber mallet thumpin me on the chest with each shot...started to blink and flinch w each shot after only a couple mags with the thing...

Loki999 Posted March 2, 2011 Author Share Posted March 2, 2011 Im picking up the gun this afternoon I'm going to start without slidelighting en without extra holes. Today is a good day Link to comment Share on other sites More sharing options...
38supPat Posted March 2, 2011 Share Posted March 2, 2011 Yes, the original port design was intimidating... Lol...I just noticed from the Pic how far back the RO is actually standing.... Link to comment Share on other sites More sharing options...
Loki999 Posted March 3, 2011 Author Share Posted March 3, 2011 Wow nice picture, i picked my gun up yesterday and im very happy with it. I shot 200 rounds for accuracy en 50 rounds on a close target. I'm very impressed with the accuracy and how easy the gun shoots, ill give it a try for some time without hybridholes. next trainingsession tommorow, training stages. Thanks for all the info everybody! Link to comment Share on other sites More sharing options...
bill d Posted March 3, 2011 Share Posted March 3, 2011 Loki, post a picture of your Infinity! How many barrel ports and what comp (Infinity's 2 port or 3?) I know you'll be pleased. Pat, is that picture with the original IMM or the top end you put on after? Link to comment Share on other sites More sharing options...
38supPat Posted March 3, 2011 Share Posted March 3, 2011 That's the origional Link to comment Share on other sites More sharing options...
Loki999 Posted March 3, 2011 Author Share Posted March 3, 2011 (edited) This is her:) No barrelports( yet) an 2 chambercomp. After a few months the gun will be titaniumnitrated. @Pat was that the early model IMM with the Tribirdbarrel?

38supPat Posted March 3, 2011 Share Posted March 3, 2011 Yeah that's the original tribrid barrel with 3n37 Link to comment Share on other sites More sharing options...
larry cazes Posted March 3, 2011 Share Posted March 3, 2011 With the full complement of holes these can be a nightmare of blast and noise for the RO. I have actually given the clock to others while running folks with these on stages with enclosures that have to be shot from. You will not make friends with one of these Link to comment Share on other sites More sharing options...
m1normando Posted March 4, 2011 Share Posted March 4, 2011 My IMM has the Tribrid II barrel and is the flattest shooting gun I have. The accuracy is unbelievable. Link to comment Share on other sites More sharing options...
