  1. Slowing the rearward movement of the slide is only a small portion of the perceived problem you are identifying. What you suggest or think is happening that your mag spring cannot move the round up fast enough for the slide to catch and chamber it is more of a forward slide speed problem. This could be caused by a bottoming out recoil spring not allowing the slide to move far enough back and with a strong recoil spring the dwell time is to short to pick up the round. I have several compact 1911s in 9 and 45 and they all have functioned fine without making modifications or changing springs. As to adding a comp or barrel holes to decrease slide travel speed, you are trying to apply a product or feature that has never been intended nor was designed to meet that criteria. The total mass of the moving object along with a proper springs is what needs to be studied. A lightened shorty open gun slide speed is probably faster than most guns but the timing and dwell time is what makes them work not the comp or barrel holes.
  2. Thinking of adding popple holes to 9 major gun but it has a cone comp. I am sure it can be done but just wondering if anybody has done popple holes with a cone comp? If so pictures and some information on how or who did them would be appreciated.
  3. Make sure you put a dab of grease on the bottom of the locator slide where it sits in the tool head. It needs to stay put and not bounce around when the brass falls down on it. Just enough to make it stay put and not move around when the machine is operating but can float and move when a piece of brass is inserted.

    Winnequah in Lodi which is 1/2 hour north of Madison up the interstate has a USPSA match the third Saturday of every month. Outside in the summer and inside in the winter. We will be having our monthly match this Saturday. Registration is 8 shooting starts at 9. Come on out to participate or just to watch. Please enter the range at the south gate (2249 Lang Drive, Lodi) and follow the signs to Ranges A – G, veer left at the tee by the plinking range. http://winnequahgunclub.org/ Also go to wisconsinshooters.com it list all of the events under the calendar page and has links to the clubs. I will pm you with more info.
  5. So has anyone had problems with their PCC 9mm hitting the primers very hard and sometimes even piercing them? This is not a overpressure problem as the loads have been chrono and are 134-136 PF. Have tried factory loads and reloads and all of them show the primer being hammered very hard. What is also odd is that it is CCI SP primers that are being pierced more than the WIN SP primers. New Frontier Armory lower, their heavy bolt group, their 16" barrel and standard upper receiver CMMG LPK. First used standard buffer and spring primer problem. Then changed out to heavy 6.5 oz longer buffer. Bottoms out rearward 1/8 - 1/4 past bolt release. No change still occasional pierced primmer but very deep hard hit primers. Reduced hammer spring tension for testing purpose. Appears to lessen the heavy hit but still more than what is acceptable and still found a pierced CCI primer out of 50 rounds. So is it a case of the hammer spring to strong for SP primers or as someone else stated in a different thread the hammer is not bottoming out against the back of the bolt. I need to check that yet but wanted to see if anyone else has seen this.
  6. The Area 5 match is just around the corner and we are looking for a few more staff so if you are interested send an email to area5staff@gmail.com for questions.

    '65 427 Shelby Cobra everyday all day Full custom Hot Rod or Rat Rod?
  9. I bought this one and it is working out pretty good. Only thing about it is it does not zip fully open to lay the guns out only the ends open and you slide gun in and out, may be a stopping point for some, I thought it might be a hassle but so far it hasn't been a big deal. It is heavy duty and even comes with built in rain cover. http://www.cabelas.com/product/cabela-s-52-tac-gear-utv-double-gun-case/1755643.uts?Ntk=AllProducts&searchPath=%2Fcatalog%2Fsearch.cmd%3Fform_state%3DsearchForm%26N%3D0%26fsch%3Dtrue%26Ntk%3DAllProducts%26Ntt%3Datv%2Bgun%2B%26x%3D10%26y%3D6%26WTz_l%3DHeader%253BSearch-All%252BProducts&Ntt=atv+gun+

  11. Good luck with your recovery. I have had 3 back surgeries all for herniated disc. First two were 4 months apart and third was 16 years later. Major difference in those 16 years on recovery due to new procedures and technology. Hang in there you will be back shooting in no time just moving a little slower for awhile. You going to make Area 5 this year?

    Right Northern state climate or southern state climate?
  13. Not sure if I am following you correctly, are you expecting a shell to be released onto the carrier when you push the bolt release? The button on the side releases the bolt on the M3K it does not release a shell. A shell is released onto the carrier when the trigger is pulled which allows the latch to move to the side and a shell is ejected onto the carrier, the shell then pushes the latch back over to retain the next shell in the mag tube.
