thanks for the info gentlemen. i did find this:
Chapter 140, Section 131FA
(v) temporary license issued under this section shall be marked “Temporary License to Carry Firearms”, shall clearly indicate whether it is Class A or Class B and shall not be used to purchase firearms in the commonwealth as provided under section 131E. Neither a large capacity firearm nor large capacity feeding device therefor may be carried unless such person has been issued a Class A license; provided, however, that the colonel may permit a Class A or Class B licensee to possess large capacity rifles or shotguns or both, and such entitlement shall be clearly indicated on such license.
if i am reading this correctly this pertains to long guns and not pistols???? there is no mention of pistols. can someone point me to the specific law regarding pistols and "Non-Res Class A high capacity LTC" for this only specifies large cap rifles and shotguns.
