The firing pin stop is just a “little extra”, it never (or should never) be the difference between safe and unsafe. Lock time is a function of about 90% slide weight, and only around 10% springs (recoil and hammer). Which is probably why Colt added a full length solid rib to the slide of my Delta Elite. How about the timing of the barrel and slide separating ways? Jack Huntington believes that if one delays the disengagement of those two via changing the depth and geometry of the barrel/slide locking lugs one effectively increases the slide weight or mass for part of the cycle by keeping it mated with the barrel and by extension the barrels weight/mass for the most critical microseconds of the rearward movement of the slide assembly. Do you concurr with that theory and practice? In the case of my DE, we changed the barrel to one that suppported more of the case and fit the barrel in such a way that it remains locked to the slide a bit longer for that effect. Went with a nice stiff single recoil spring as well for good measure. I�m going to go out on a limb and say I squarely don�t know. I�d love to sit down with him to gain a greater understanding. Simply setting the barrel deeper into the locking lugs could conceivably cause as many problems as it solves�or at least it seems that way to me. I�ve never tried it because I was taught to install a barrel the right way every time and to end up with a barrel significantly deeper into the lugs than normal would take a whole lot of extra work, so I�ve never ended up there even on accident. I�ve heard of people taking the link slightly over center to create a �moment� about the axis, but again, I don�t know the specifics of how that�s actually done, and how well it works. That�s an area where I just have never gone. When Jack is done the results are outstanding, he definitely knows what he is doing ![[Linked Image]](http://i33.photobucket.com/albums/d62/jwp475/DSC01574_zpsdfbbc044.jpg)

Mark do you have a custom barrel in your delta elite? Some say not to shoot their ammo in the delta due to the rampless barrel? Yes sir, I do. It is a custom fitted - by Jack Huntington of JRH custom guns - Storm Lake barrel. It and the pistol overall are FAR more accurate and capable than I am as a pistol shooter. I feel like a Jr. High violin student holding a Stratovarious Violin!

The problem is that many 1911's leave the factory with poor barrel slide lock up

I understand that when Smith and Wesson went to make their 1006/1076 guns, they increased the weight of the slide. The recoil spring is very stiff as well.
To my knowledge, the 1006/1076 guns have had no problems with any reasonable 10mm ammo. E

Which is probably why Colt added a full length solid rib to the slide of my Delta Elite.
And therein lies the main reason you gun is more manageable; all the rest is secondary though fooling with the barrel lug engagement could be considered directionally right, but, IMO they are relatively small factors. (I have been around a lot of 1911 'smiths & armorers & none of them have ever mentioned needing to do it) Why do you think that most really successful bullseye (softball) shooters put ribs on their 1911's for the 45 class? To slow down the slide, allow the use of very soft springs & VERY mild loads, as in 3.2 gr of BE with a 185-200 gr bullet.............and the guns will function just fine. MM

here's the smiley case I mentioned. The load that did it ran a 155 at 1425 fps... ![[Linked Image]](http://i712.photobucket.com/albums/ww127/tex_n_cal/DSCN3000_zps3ad9201a.jpg)

MM You are right many do not, but you do not need a spring as heavy you do when you do not. Mark has a 20 pound spring now which is lighter than the double spring set up that Colt used, yet he is not throwing brass 30" as he was before and the gun is not battering itself as bad either

Mark, does your Delta look like this one? (Minus the adj sights and Gold Cup trigger) ![[Linked Image]](http://i712.photobucket.com/albums/ww127/tex_n_cal/DeltaGoldCup_zps96e15650.jpg) if so that is the flat top slide used on the "enhanced" Gov't models, including the Deltas.

By lengthening the lockup time pressure is lower when it unlocks thus slowing the slide velocity. I do not have a heavier slide on my 45 Super and I use an 18.5 pound spring

I'd surely like to examine your gun & make some measurements..........too bad we are so far apart.
What bullet weight & what velocity are your 45 Super loads?

Do you have load data for Super 255 cast bullets? I have a 625 JM that I'd like to try something along those lines in..... IIRC Buffalo Bore offers a stout .45 super load but the meta plate had to be kind of small to function in an auto pistol.... I have a mold that cast a wide flat nose at that weight... PM inbound

I wonder if it had been called a 10X25 would made a difference or maybe a 40 by 25 would have made it more attractive. Just speculating on what makes people take somethings and pass on other things. Cheers NC

I had not thought of that one, but it is a good one! 10x25.... I LIKE it! Even though it does not have magnum in the name, and that would fit. How about 10x25 Magnum?

If they renamed it the .40 Smith and Wesson Magnum it would be all the rage for two years.

I think the 10mm would have sold much better IF... After reading 155 replies, I can honestly say that the answer is that had all the 10's been 45's they would have sold much better.  MM

16 pages of banter......the 10 can't be all bad.
I would not buy something that runs on any kind of primer given the possibility of primer shortages and even regulations. In fact, why not buy a flintlock? Really. Rocks aren't going away anytime soon.
