DocMedic Posted July 30, 2015 Share Posted July 30, 2015 So that Carry Optics is a thing now. What are the pro's and con's of running the different size guns? Before I took OPEN seriously I built a M&P pro with a slide ride Deltapoint and a comp. Taking off the comp shouldn't be a issue by a gun smith, but I seem to remember that the gun just felt sluggish when using minor loads as in you were waiting for the dot to come back. I remember sometime back that people where recommending using a standard size M&P as it seem to "snap back" faster with no waiting of the slide.

racingjoe27 Posted July 30, 2015 Share Posted July 30, 2015 It's only provisional, why buy or build a gun for a division that isn't actually a "thing?" IMO leave the division for what the association needs it for, more membership! Get your friends with dotted m&p's to come play. Oh and to actually answer your question, in the spirit of the division you would want a 4.25 with a threaded barrel (read longer)... Link to comment Share on other sites More sharing options...
DocMedic Posted July 31, 2015 Author Share Posted July 31, 2015 I should clarify a little, I wouldn't be buying a new M&P for the division, I have several in the safe of all sizes. Even though its only considered a provisional division right now doesn't mean I wouldn't think of taking it seriously. If anything I'm trying to gain a little more information on peoples experience using long slides vs standards slides when using Slide Mounted red-dots, since CORE pistols have been out for a little more then a year now.

BritinUSA Posted July 31, 2015 Share Posted July 31, 2015 My XDM has the 5.25 slide, it feels slower to me than my Open gun but I would not call it sluggish, I don't feel like its slowing me down when I shoot, but the dot came back a lot faster on my .38Super Open gun.

GOF Posted July 31, 2015 Share Posted July 31, 2015 Doc, I'm currently playing with a ported M&P 5 inch CORE and a 8 MOA JPoint. I use a 147 Xtreme RN bullet. The 880 fps load I used with a 4.25 non-ported M&P is sluggish in the 5 inch. I upped the powder to run that bullet at 910 fps. It recoils more, but snaps the dot back faster. Although it has a sharper recoil than the 880 fps load, the splits on double taps are noticeably faster and the double taps are tighter. That is freestyle. Weak & strong hand is not as much "fun". I realize the ported barrel won't play in Carry Optics. I think... with a non-ported barrel in CO..... I would play with the 880 fps load and check accurate split times. If a 5 inch is available, compare them. Tuning the load to "The Dot" would be an important factor. Link to comment Share on other sites More sharing options...
BritinUSA Posted July 31, 2015 Share Posted July 31, 2015 I think the advantage to the longer slide is obviously in the increased sight radius, as that is not an issue with the dot, it sounds like the 4.25 option may work better. I might think about getting a shorter XD and trying it out, though I'm happy with the 5.25 at the moment. Link to comment Share on other sites More sharing options...
atbarr Posted August 10, 2015 Share Posted August 10, 2015 I'm thinking of using either my G21 or my G30SF. Will I handicap myself with the G30SF in Carry Optics? Link to comment Share on other sites More sharing options...
recoilchamp Posted August 13, 2015 Share Posted August 13, 2015 I haven't compared myself, but another advantage the long slide might have is more weight in the front, reducing muzzle rise. Link to comment Share on other sites More sharing options...
KSwift Posted August 23, 2015 Share Posted August 23, 2015 Look up the reasoning behind using shorty Open guns, same basic arguments. Some folks specifically build sub 5" 1911/2011 style customs. Some also build 6" ones too... Link to comment Share on other sites More sharing options...
Flash74 Posted August 23, 2015 Share Posted August 23, 2015 Run what ya got, especially for a provisional division. If the slide is feeling sluggish go up on your recoil spring. For me a 15lb spring feels the best in 9mm. The 13 and 11lb springs just felt too slow. In 40, a 13lb feels the best for me. Run all the spring weights you have on the clock. I bet it won't make much of a difference. Pick the one that feels the best to you. Link to comment Share on other sites More sharing options...
