Removing Query String After the Redirect. 90% done with RewriteRule

Any Idea's how to remove the Query String when using a rewriterule?

Hey Guys.

Need to redirect old links that use the ?p=stuff in google.

I got this much.

RewriteCond %{QUERY_STRING} ^p=plumb_supply
RewriteRule ^ http://www.example.com/plumbing_supply.htm? [QSA,R=301,L]

but it makes the URL

http://www.example.com/plumbing_supply.htm?&p=plumb_supply

Any Idea's how to remove the Query String? I thought that is what the QSA did?

QSA appends it.

A question mark on the end of the target URL will clear the query string.
