  1. My understanding is that a face to face transfer between private paties above 21 years old requires nothing - no difference between handgun and rifle. However, I always provide or get a bill of sale and get a photocopy of the other persons drivers license and CWL, if they have one. If uncomfortable, any gun or pawn shop will run the transfer for you for anywhere between $35 and $75.

  2. An awesome speed vs prone was stage 13 at the US IPSC Nationals. Essentially, the penalty for slowness was to force the shooter to get prone to engage three targets. Check it out at:

    Note the differing strategies from removing mag prior to opening box (in my opinion, the best strategy), to just shooting the three targets last in the prone position.

    Looks like a great challenge and I am all for it.

  3. Kevin - thanks for the update. I too put my M&P Pro 40 - 5" in the scale. With the large blackstrap, magazine and an uncaptured tungsten guide and spring (without mag well), it weighed 30.25 ounces. Subtracting the 1 ounce delta of the uncaptured tungsten guide and spring vs the stock captured guide rod, my M&P Pro 40 weighs 29.25 ounces, which is above the published weight of 27.42 ounces (part of the overweight may be due to the internal trigger job, but not all).

  4. I would like to restart this discussion. I run a M&P Pro .40 – 5” in USPSA limited and have a new M&P Pro 9 – 5” to run in USPSA production.

    I would like to add a SSS uncaptured guide rod, either in steel or tungsten.

    Of course, the challenge as discussed in the posts above, is that after all modifications, the gun must weigh no more than 2 ounces over the weight listed on the USPSA Approved Production Handgun List – 27.44 ounces. As you might imagine, I would prefer not to get moved to open in the upcoming Level 2 matches at Frostpoof.

    Last night I weighed my new gun and its various parts using a digital kitchen food scale:

    Complete M&P

    · With magazine and large backstrap: 28.82 ounces (817 grams)

    · With magazine and medium backstrap: 28.57 ounces (810 grams)

    · With magazine and small backstrap: 28.43 ounces (806 grams)

    Thus, my gun with any backstrap is over the “standard” weight by a minimum of approximately 1 ounce and leaves me with only one additional ounce to play with. In reality, I use the large backstrap and am left with approximately 6/10 of an ounce to play – planning on trigger work, an APEX failure proof extractor and an uncaptured guide rod and spring.

    Parts of the M&P

    · Captured guide rod and spring: 0.92 ounce (26 grams)

    · Frame with large backstrap: 7.20 ounces (204 grams)

    · Slide/Barrel/Guide Rod and Spring: 18.59 ounces (527 grams)

    · Magazine: 3.07 ounces (87 grams)

    SSS has e-mailed me that the weight of the steel guide rod is 0.84 oz. and the weight of the tungsten guide rod is 1.7oz. Depending on brand, an uncaptured recoil spring weighs between 0.18 ounce and 0.32 ounce – I will assume the higher number. Thus, the uncaptured guide rod and spring total 1.16 ounces for steel and 2.03 ounces for tungsten. Therefore, the net increase by going from a captured to an uncaptured guide rod is 0.24 ounce for steel and 1.11 ounces for tungsten.

    As you can see, substituting a steel uncaptured guide rod is not a problem and substituting a tungsten uncaptured guide rod would put my gun over the maximum weight by just over 1/2 ounce. Note that the overweight issue is not even solved if I go with the smaller backstrap – my gun would still be over the maximum weight by just over 1/10 ounce . All of this would not be an issue if the weight listed on the USPSA Approved Production Handgun List was accurate or closer to accurate.

    I am interested in how others have modified their production M&Ps in light of the 2 ounce restriction and the inaccurate base weight on the USPSA Approved Production Handgun List.

    Also, it seems that in another thread (http://www.brianenos.com/forums/index.php?showtopic=183216), Ngthwk1911 stated that an update to the weight of the M&P Pro was in the works. Can you clarify what actions have taken, who is working on this issue and any feedback that has been received?

    Thanks in advance.
