Glock light on a Sigma?

[citori59]

Please forgive me if this is common knowledge or has been covered before, but will a tactical light meant for a Glock fit a Sigma 40VE?

Does your sigma have a cross slot under the frame for the light to lock onto. Msot just have 2 rails on the side of the frame in this case a Glock light will not fit.
