  1. I too recently got a Para Pro Comp 40. I mostly shoot USPSA Production with a Glock 35 (reload to .40 minor), but wanted to get a reasonably priced 1911 in .40 to occasionally compete in Single Stack division. The fit and finish of this Para is excellent. No machine marks or burrs anywhere. No slide rattle from side to side, but not too tight either. I really like the Ion Bond finish on top of the Stainless Slide, Stainless Barrel, and Stainless Frame. However, the trigger pull is HEAVY and rough. Here's a breakdown of the changes I made at home to get this 1911 ready to my liking for competition:

    Installed a .250" Diameter Full Length Guide Rod and Plug from EGW, to run flat ISMI 17# recoil spring (feels like a Wolff 14#)

    Removed the Series 80 Firing Pin Safety Mechanism (out of frame and slide)

    Installed a .065" Metal Filler Plate (from Brownells) in the frame to take up the space occupied by the Series 80 leverage bars

    Installed a Wilson Titanium Firing Pin (.065" tip) with a Wolff Heavy Duty Firing Pin Spring

    No adjustment necessary on the stock Extractor (EGW Heavy Duty)

    Installed a Wilson Bullet Proof Slide Stop

    Lightly Polished Barrel Feed Ramp with a very small amount of Jewelers rouge and a Dremel tool with a felt polishing pad

    Lightly Polished the top end of the Disconnector, and the bottom face that contacts the back of the trigger

    Lightly Polished the top edge of the Sear (using a polishing block used for finger nails)

    Lightly Polished the face of Hammer

    Lightly Polished the contact points of the Grip Safety arm

    Lightly Polished the back face, top and bottom arms of the trigger bow

    Installed a Wolff 16# Hammer Spring

    Installed a EGW Titanium MSH Cap

    Installed TechWell "TGO-IPSC" Magwell (Black), with their Black Diamond G10 Grips

    Installed a Wilson SS Extended Mag Release with a slightly reduced weight release spring

    Lubed the Rails, Inner part of Bushing, Outer Barrel, and Lugs using "Gun Butter"

    Later, I may install a higher quality Sear, Disconnector, and Hammer from either Wilson or Harrison

    It now feels like its running on ball bearings. The trigger break is now smooth, crisp and approximately 3.5 lbs. The gun has run flawlessly in practice using "Tripp Corey Mags 10mm", shooting MG 180gr CMJ loaded to 1.180" with a 171 Power Factor. The real test will come when I shoot it in an actual match. I may wait to get this Para in match until after the Area 6 match in April. Overall, and so far, I'm very pleased with the Para Pro Comp 40. Also, the adjustable rear sight and fiber optic front have a great "feel" and sight picture. The width of the front sight is a perfect match to the notch on the rear sight, and the fiber diameter is small enough to not "Halo" and distract. If you don't like the Fiber Optic front, Dawson Precision makes a solid Black front sight for a Para, with options for height and width.

    exactly what I would do if I had one!

  2. no...wait. I have a Kimber 9mm and although I dont recall the measurment, I could fit a 40 case into the breechface. Now saying that, the bottom where the round slides up, the area next to the extractor, will not let a 40 case slide up, only a 9mm case, which I do remember is .357 or something like that.

    If you look here on the forum, you will find others that have mentioned that Kimber used the same breechface size for both 40 and 9. And while I am not a gunsmith, it seems to me that if only the bottom is tighter to only let a 9mm case up into the breechface and the gun works...no problem, right? Because my gun shoot 9mm alright!

    So, by opening up that area to allow a 40 case up into the breechface, a 9mm gun can be made to shoot 40sw.

    IMO

  3. Well does your brother have any magazines that were legal before the 10 round law came into effect? If you legally owned them before 2000 you are good to go. Just go down to the matches and check it out and see what everyone else is doing. Its pretty easy to get into the sport even here in Cali.

    how can you tell when the magazine were made? no serial number, no date of mfg. so how can law enforement tell you have illegal magazines?

  4. thanks for that last post. when you mean AL, you are talking about the aluminum comp, correct? question about the barrel being proud, was that done so that the gases would not erode or wear away from the front face aluminum?

    thanks

    there could be more interest in this concept, since it was debated last year on the forum, when it was announced that rules in Limited were being lifted. there was alot of talk about a "solid comped" Limited gun.

    sooooo, more photos would be great!!!!!

  5. 16" mid length with rifle buffer and JP buffer spring. BCG is full weight. Ammo chronos at 3000 fps. Does not lock back with empty magazine and will not manual lock back when pulling the handle back.

    I can see through the ejection port that the BCG is not going back far enough for the latch to catch on the front of the carrier.

    Could the spring be too long?

    Am not too concern about the last round not lock back, new magazines could fit that but pulling back the handle and seeing the carrier not going back enough does concern me.

    Any ideas.

    thanks

  6. Based on the title of the thread, was hoping you were asking about locktite on barrel extension/upper receiver interface, which some folks advocate, but NOT on barrel nut. The gas tube, if using a mil spec barrel nut, makes this unnecessary.

    Mark

    yes that is correct not on the barrel nut threads but on the extension.

    any locite?

    thanks

  7. there is alot of posts of this topic. I did read everything I could on this forum about loading .223. I have a 1050, bought a RT trimmer and tried a setup like you describe.

    what I came to the conclusion (for me), without going into a long story of the steps I did. I finally do it this way and it works well. and since you have two loaders 1050/650, you can easily do the first part on the 650.

    on a rockchucker with lubed brass:

    1. decapping (using a Lee 40SW die) it only decaps

    2. FL /trim with the RT trimmer

    3. since the RT trimmer only FL and reduceds the neck smaller than you want, about .009's smaller than you need,

    4. I run all the brass again using only the FL die, screwed down enough, so that ONLY the expander plug runs through the necks to reopen the brass to about .222. Thats enough neck tension to hold the bullet, which is about .224.

    You can determine the tension by reduce the size of the expander plug on a drill, using a file and sandpaper. Measure first see where you are at on the expander.

    .

    Tumble

    Then run load on the 1050:

    1. swage

    2. prime

    3. load powder

    4. seat bullet

    thats it!! rounds really dont need the crimp but if you like to crimp, then on the last stage add the crimping die. but really not needed.

    no tumbling needed either, since your not handling lubed brass or shavings on the brass, when loading on the 1050.

    I don't shoot thousands and thousands of 223 a year but you would be surprise how quickly you can do six to eight hundred rounds on the Rockchucker before going to the 1050.

    if your doing more brass, doing this way in your spare time before loading on the 1050 is not a big deal.

    hope this helps

    with this method I can get sub half MOA @ 100yds.

  8. mine is like the last photo with the cotter key. No I would say there is medium pressure on the spring. I was loading 223 with H335 powder. One thing I did notice was the square cube that rides in the slot for the powder measure. I was sort of...angle in the corners so I replaced it.

    Also on mine since it so old, in the last photo, the longer slot where the rod rides on, had a rough surface with bumps. So I sanded it down and now I grease that whole area where the rods moves in.

    I have switch to loading 45 and will see if I get the same slamming effect.

    thanks

  9. I removed the BCG and I can see the exhaust inside of the chamber and up along the wall of the receiver escaping through the gas tube hole. The end of the gas tube is shinny clean about a 1/4 inch, the rest of the area is covered with soot. That tells me that gas is escaping from the chamber, right???

    Could it be that my handloads, I bumped the shoulder too far down, in an effort to ensure that they chamber and extract without getting stuck?????

    The loaded rounds fit the Dillon gauge and do not fall below the lower limits. About even or maybe slightly below.

    thanks

  10. just got back from the range and the ran but after 50 or so rounds the bolt is not stripping the next round. I can hand cycle but not shot after shot.

    When I remove the magazine, I can see signs of gas on the top rounds. I can also see between the receiver and handguard the gas tube is black from soot. there is no gas leak from the gas block, only from the area I mentioned.

    So, what should I look for when I dismantle the upper?

    thanks
