There isn't any. The bill's still going through the process of being passed, so possibly it's just a bit of disinformation. Everyone else is simply repeating what they heard, they haven't actually read the bill.

Cities can only write firearm-related ordinances as allowed by the state under 21.750 RSMo. That section is not changed by SB 656. Ordinances prohibiting "the carrying of a firearm" that would include lawful concealed carry (with or without a permit) would not conform with state law (which does have preemption).

I think the problem is that the Senate passed the bill then sent it to the House, the House made several changes one of which was the provision that you were limited to only were OC was legal. When it got back to the Senate it was rejected as amended and sent back to the House, I believe that provision was removed on the final bill that was passed by the Senate. So I think people may be quoting an old version of the bill and thats were the error comes in.

I followed this bill closely, and I never saw an amendment to SB 656 that included such language. The House Committee Substitute is here, but it wasn't the last version that actually came out of the House. The last version was a further amended HCS, the full text of which is not posted; but you can easily check the language of those additional amendments to the HCS in the House Daily Journel of May 5th. (They start on page 32 of the pdf.)

Edited to add: When the Senate rejected the HCS as amended, it was not sent back to the House; instead, the Senate requested the House "recede or grant a conference," and the bill went to conference. This is where it was negotiated and came out in its final form, the current version that was "Truly Agreed To and Finally Passed" that awaits a decision by the governor.

SB 656 was delivered to the governor today...so, he needs to sign or veto by July 9, looks like.

Effective dates...

There is an Emergency Clause for immediate enactment of Section 571.104, which has to do with the military permit renewals. This section would immediately become law if and when the governor signs the bill.

Enactment of Section 571.030 would be delayed until January 1, 2017. This section has to do with carrying concealed weapons under subsection 1 (permitless ccw), additional persons being exempted from crimes under subsection 5, and changes in penalties under subsection 8.

All the rest would be enacted in 2016 on the usual date: August 28 if the governor signs the bill or leaves it unsigned, or ~October 14 if the legislature has to override the governor's veto. (Thirty days from the Veto Session on September 14 would be October 14.)

------

HB 1765 was also delivered to the governor today. In addition to everything else covered by this bill (which is extensive), it would change Section 513.430 to exempt firearms, firearm accessories, and ammunition up to $1,500 from attachment and execution.

So June 25th no permit carry is good to go unless its vetoed.

Wouldn't take effect until January.....last page in the bill.
